Abstract
Description
Technical Field
[0001] This application relates to the field of drainage pipeline construction equipment technology, and in particular to a collapse prevention support device for drainage pipeline construction. Background Technology
[0002] When constructing drainage pipelines, trenches need to be excavated to accommodate the pipelines. However, during the construction of drainage pipelines, especially in areas with loose soil or complex geological conditions, soil collapse is a common and serious problem. In order to prevent the soil from collapsing, support structures need to be installed in the trenches for support.
[0003] In existing drainage pipeline construction, wooden piles or steel supports are generally used as temporary supports. Although this method is low-cost and readily available, it cannot adapt to complex terrain, is not convenient to adjust according to the height of the trench, and has poor applicability to different drainage pipeline construction trenches. Therefore, an improvement has been made to an anti-collapse support device for drainage pipeline construction. Utility Model Content
[0004] In view of the shortcomings of the prior art, this application provides a collapse prevention support device for drainage pipeline construction, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.
[0005] To achieve the above objectives, this application provides the following technical solution: a collapse-prevention support device for drainage pipeline construction, comprising several bases symmetrically distributed within a trench, with a column fixedly connected to the top of each base. A lead screw is rotatably mounted inside each column via a bearing. A bevel gear is fixedly connected to the lower end of the lead screw, and a bevel gear is meshed with one side of the bevel gear. An internal hexagonal rotating component that drives the bevel gear is rotatably connected to the side wall of the column. A telescopic column is threadedly connected to the outer surface of the lead screw inside the column. A fixed seat is fixedly connected to the inner wall of the telescopic column, and a crossbeam is slidably inserted into the top of the fixed seat. Two symmetrical telescopic columns are fixedly connected via the crossbeam to form a support frame. A protective plate is provided on the outer side of each telescopic column.
[0006] By adopting the above technical solution, a stable support frame is formed through the cooperation of the base, column, telescopic column, fixed seat, and crossbeam, providing solid support during construction. The rotation of the internal hexagonal rotating component drives the second bevel gear to rotate. Since the first and second bevel gears mesh, the internal hexagonal rotating component can drive the screw to rotate synchronously. This allows the telescopic column to extend and retract, adjusting its height. In other words, the height of the support device can be flexibly adjusted according to the actual conditions of the construction site to meet the construction needs of drainage pipes of different depths and diameters. The installation of protective plates can effectively prevent soil collapse and gravel falling, ensuring the safety of construction personnel.
[0007] As a preferred technical solution of this application, the inner walls of both sides of the column are symmetrically provided with grooves, and the outer walls of both sides of the telescopic column are symmetrically provided with protrusions. The protrusions are slidably connected to the grooves, and the protrusions are adapted to the grooves.
[0008] By adopting the above technical solution, the cooperation between the convex strip and the groove ensures that the telescopic column can only move vertically up and down along the central axis of the screw, thus preventing the telescopic column from rotating.
[0009] As a preferred technical solution of this application, the fixed base has an adjustment groove inside, and a fixing unit is provided inside the adjustment groove. The fixing unit includes a sliding rod that is slidably inserted into the adjustment groove. An adjustment block is fixedly connected to the rear end of the sliding rod. The adjustment block is fixedly connected to the inner wall of the adjustment groove by a spring. The front end of the sliding rod slides through the adjustment groove and is inserted into the inside of the crossbeam under the elastic force of the spring.
[0010] By adopting the above technical solution, the position of the sliding rod is adjusted by the cooperation between the spring and the adjusting block. When the sliding rod slides into the inside of the crossbeam under the action of the spring, the crossbeam can be fixed inside the fixed seat. When the sliding rod is pulled out from the inside of the crossbeam by pulling the adjusting block, the crossbeam can be detached from the inside of the fixed seat, which provides convenience for the installation or disassembly of the crossbeam.
[0011] As a preferred technical solution of this application, the crossbeam includes a fixed rod, a threaded rod is threadedly inserted into the fixed rod, and a snap-fit block is rotatably connected to the ends of the fixed rod and the threaded rod that are far apart from each other.
[0012] By adopting the above technical solution and utilizing the threaded connection between the fixed rod and the threaded rod, the overall length of the crossbeam can be adjusted, allowing the width of the support device to be flexibly adjusted according to the actual conditions of the construction site, thereby further improving the applicability of the support device.
[0013] As a preferred technical solution of this application, the snap-fit block is slidably inserted into the interior of the fixing base, the lower end of the snap-fit block is provided with a fixing hole, the front end of the sliding rod is located inside the fixing hole, and the diameter of the sliding rod is adapted to the inner diameter of the fixing hole.
[0014] By adopting the above technical solution, the snap-fit block is fixed inside the fixing seat through the cooperation between the sliding rod and the fixing hole, thereby realizing the fixed installation of the crossbeam.
[0015] As a preferred technical solution of this application, the outer wall of the telescopic column is fixedly connected to a connecting seat, and the inner wall of the protective plate is fixedly connected to a connecting block, and the connecting block is fixedly connected to the connecting seat by bolts.
[0016] By adopting the above technical solution, the protective plate and the telescopic column are fixedly connected together.
[0017] As a preferred technical solution of this application, the outer walls of the two sides of the protective plate are symmetrically provided with tenons, and tenons are slidably inserted into the interior of the tenons, and the two adjacent protective plates are fixedly connected by the tenons.
[0018] By adopting the above technical solution, adjacent protective plates are fixedly connected through the cooperation between tenons and mortises, thereby splicing several protective plates together to form a complete whole, which enhances the load-bearing capacity of the support device and improves its safety.
[0019] As a preferred technical solution of this application, a positioning hole is provided through the upper surface of the base, and an anchor nail is slidably inserted into the positioning hole.
[0020] By adopting the above technical solution, the base is fixedly installed inside the trench by sliding and inserting anchor nails inside the positioning hole.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0022] 1. In this utility model, a stable support frame is formed by the cooperation between the base, column, telescopic column, fixed seat and crossbeam, providing solid support during construction. The rotation of the internal hexagonal rotating component drives the second bevel gear to rotate. Since the first bevel gear and the second bevel gear mesh, the internal hexagonal rotating component can drive the screw to rotate synchronously when rotating. Thus, the telescopic column can be telescopically adjusted to adjust its height through the rotation of the screw. That is, the height of the support device can be flexibly adjusted according to the actual conditions of the construction site to meet the construction needs of drainage pipes of different depths and diameters. By setting up protective plates, soil collapse and gravel falling can be effectively prevented, ensuring the safety of construction personnel.
[0023] 2. In this utility model, the position of the sliding rod is adjusted by the cooperation between the spring and the adjusting block. When the sliding rod is slidably inserted into the inside of the crossbeam under the elastic force of the spring, the crossbeam can be fixed inside the fixed seat. When the sliding rod is pulled out from the inside of the crossbeam by pulling the adjusting block, the crossbeam can be detached from the inside of the fixed seat, which provides convenience for the installation or disassembly of the crossbeam.
[0024] 3. In this utility model, the threaded connection between the fixed rod and the threaded rod allows for adjustment of the overall length of the crossbeam, enabling the width of the support device to be flexibly adjusted according to the actual conditions of the construction site, thereby further improving the applicability of the support device.

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0034] like Figure 1 - Figure 5 As shown in this embodiment, a collapse-prevention support device for drainage pipeline construction includes several bases 1 symmetrically distributed inside a trench. Each base 1 has a column 2 fixedly connected to its top. A lead screw 3 is rotatably mounted inside the column 2 via bearings. A bevel gear 5 is fixedly connected to the lower end of the lead screw 3. A bevel gear 6 is meshed with one side of the bevel gear 5. An internal hexagonal rotating component 7, which drives the bevel gear 6, is rotatably connected to the side wall of the column 2. A telescopic column 4 is threadedly connected to the outer surface of the lead screw 3 inside the column 2. A fixed seat 15 is fixedly connected to the inner wall of the telescopic column 4. A crossbeam 18 is slidably inserted into the top of the fixed seat 15. Two symmetrical telescopic columns 4 are fixedly connected via the crossbeam 18 to form a support frame. A protective plate 11 is installed on the outside of the support. During use, a stable support frame is formed by the cooperation between the base 1, column 2, telescopic column 4, fixed seat 15 and crossbeam 18, providing solid support during construction. The rotation of the internal hexagonal rotating part 7 drives the bevel gear 6 to rotate. Since the bevel gear 5 and bevel gear 6 mesh, the internal hexagonal rotating part 7 can drive the screw 3 to rotate synchronously. Thus, the rotation of the screw 3 can drive the telescopic column 4 to extend and retract, adjusting its height. That is, the height of the support device can be flexibly adjusted according to the actual conditions of the construction site to meet the construction needs of drainage pipes of different depths and diameters. The protective plate 11 can effectively prevent soil collapse and gravel falling, ensuring the safety of construction personnel.
[0035] In this embodiment, as Figure 3 As shown, grooves 8 are symmetrically provided on the inner walls of both sides of the column 2, and protrusions 9 are symmetrically provided on the outer walls of both sides of the telescopic column 4. The protrusions 9 are slidably connected to the grooves 8, and the protrusions 9 and the grooves 8 are adapted to each other. In use, the cooperation between the protrusions 9 and the grooves 8 ensures that the telescopic column 4 can only move vertically up and down along the central axis of the screw 3, thus preventing the telescopic column 4 from rotating.
[0036] In this embodiment, as Figure 4 and 5As shown, the fixed base 15 has an adjustment groove 16 inside, and a fixing unit 17 is provided inside the adjustment groove 16. The fixing unit 17 includes a sliding rod 171 that is slidably inserted into the adjustment groove 16. An adjustment block 173 is fixedly connected to the rear end of the sliding rod 171. The adjustment block 173 is fixedly connected to the inner wall of the adjustment groove 16 through a spring 172. The front end of the sliding rod 171 slides through the adjustment groove 16 and is inserted into the crossbeam 18 under the elastic force of the spring 172. In use, the position of the sliding rod 171 is adjusted by the cooperation between the spring 172 and the adjustment block 173. When the sliding rod 171 is slidably inserted into the crossbeam 18 under the elastic force of the spring 172, the crossbeam 18 can be fixed inside the fixed base 15. When the sliding rod 171 is pulled out from the crossbeam 18 by pulling the adjustment block 173, the crossbeam 18 can be detached from the fixed base 15, providing convenience for the installation or disassembly of the crossbeam 18.
[0037] In this embodiment, as Figure 4 As shown, the crossbeam 18 includes a fixed rod 181, with a threaded rod 182 threadedly inserted inside the fixed rod 181. Both the fixed rod 181 and the threaded rod 182 are rotatably connected to a snap-fit block 183 at their ends. In use, the overall length of the crossbeam 18 can be adjusted by utilizing the threaded connection between the fixed rod 181 and the threaded rod 182. This allows the width of the support device to be flexibly adjusted according to the actual conditions of the construction site, further improving the applicability of the support device.
[0038] In this embodiment, as Figure 4 and 5 As shown, the snap-fit block 183 is slidably inserted into the interior of the fixing base 15. The lower end of the snap-fit block 183 has a fixing hole 184 through it. The front end of the sliding rod 171 is inside the fixing hole 184, and the diameter of the sliding rod 171 is adapted to the inner diameter of the fixing hole 184. In use, the snap-fit block 183 is fixed inside the fixing base 15 by the cooperation between the sliding rod 171 and the fixing hole 184, thereby realizing the fixed installation of the crossbeam 18.
[0039] In this embodiment, as Figure 2 As shown, a connecting seat 10 is fixedly connected to the outer wall of the telescopic column 4, and a connecting block 12 is fixedly connected to the inner wall of the protective plate 11. The connecting block 12 is fixedly connected to the connecting seat 10 by bolts. In use, the protective plate 11 and the telescopic column 4 are fixedly connected together.
[0040] In this embodiment, as Figure 2As shown, mortise and tenon grooves 13 are symmetrically provided on both outer walls of the protective plate 11. Tenon blocks 14 are slidably inserted into the mortise and tenon grooves 13. Adjacent protective plates 11 are fixedly connected by tenon blocks 14. In use, adjacent protective plates 11 are fixedly connected by the cooperation between tenon blocks 14 and mortise and tenon grooves 13, thereby splicing several protective plates 11 together to form a complete whole, which enhances the load-bearing capacity of the support device and improves safety.
[0041] In this embodiment, as Figure 3 As shown, a positioning hole 19 is provided through the upper surface of the base 1. An anchor nail is slidably inserted into the positioning hole 19. In use, the base 1 is fixedly installed in the trench by sliding the anchor nail into the positioning hole 19.
[0042] The working principle of this utility model is as follows: When using the anti-collapse support device for drainage pipeline construction according to this application, a stable support frame is formed through the cooperation between the base 1, column 2, telescopic column 4, fixed seat 15, and crossbeam 18, providing a stable support force during construction. By rotating the internal hexagonal rotating part 7, the bevel gear 6 is driven to rotate. Since the bevel gear 5 and the bevel gear 6 mesh, the internal hexagonal rotating part 7 can drive the screw 3 to rotate synchronously when rotating. Thus, the telescopic column 4 can be telescopically moved to adjust its height through the rotation of the screw 3. The overall length of the crossbeam 18 can be adjusted by the threaded connection between the fixed rod 181 and the threaded rod 182. That is, the height and width of the support device can be flexibly adjusted according to the actual situation of the construction site to meet the construction needs of drainage pipelines of different depths and diameters. By setting the protective plate 11, soil collapse and gravel falling can be effectively prevented, ensuring the safety of construction personnel.
